... Reading data out of the device is similar to read- ing from an EPROM; it has standard CE, OE and WE inputs to avoid bus contention. Reprogramming the AT49F4096A is performed by first erasing a block of data and then programming on a byte-by-byte or word-by-word basis. Pin Configurations ...

... The boot sector is designed to contain user secure code. For the AT49F4096A, the BYTE pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE pin is set at a logic “1” or left open, the device is in word configuration, I/O0 - I/O15 are active and controlled by CE and OE. If the BYTE pin is set at logic “ ...

... ADDRESS INPUTS X DECODER READ: The AT49F4096A is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high-impedance state whenever high. This dual line control gives designers flexibility in preventing bus contention ...

... AT49F4096A 4 If the boot block lockout has been enabled, the chip erase will not erase the data in the boot block; it will erase the main memory block and the parameter blocks only. After the chip erase, the device will return to the read or standby mode. ...

... Entry/Exit” on page 13. The manufacturer and device codes are the same for both modes. DATA POLLING: The AT49F4096A features Data Polling to indicate the end of a pro- gram cycle. During a program cycle, an attempted read of the last byte loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been com- pleted, true data is valid on all outputs and the next cycle may begin. During a chip or sector erase operation, an attempt to read the device will give a “ ...
